Title:
CERAMIC SEPARATION MEMBRANE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/096398
Kind Code:
A1
Abstract:
The present invention relates to a ceramic separation membrane and a manufacturing method therefor. Specifically, the present invention relates to a ceramic separation membrane manufacturing method, which controls material characteristics of an intermediate layer through surface modification using coating, so as to improve material compatibility and interlayer adhesion at an interface at which the intermediate layer of a ceramic separation membrane meets a separation layer thereof, and thus can repeatedly produce a ceramic separation membrane with excellent quality.
